Shtefazon, SL: Targeted Weed Control from Liechtenstein

In modern crop protection, maintaining field purity while avoiding phytotoxicity is a challenge every farmer faces. Shtefazon, SL, developed by DDE Farm AG (Triesen, Liechtenstein), offers a reliable solution through its targeted, selective action. Built on the proven efficacy of Bentazone, this contact herbicide is designed to safeguard essential crops like soybeans, peas, flax, rice, winter barley, and spring wheat.

How It Works

Unlike systemic herbicides that translocate throughout the plant, Shtefazon acts upon contact. Once applied to the foliage, it effectively blocks photosynthesis within target weeds. This precision is what makes it a go-to choice for managing broadleaf weeds without jeopardizing the development of the primary crop.

Target Weeds

The product provides robust defense against a range of troublesome broadleaf species that compete for moisture and nutrients, including:

• Common ragweed (Ambrosia artemisiifolia) and Redroot pigweed;
• Common lambsquarters and Spreading orache;
• Shepherd's purse, Cleavers, Scentless mayweed, and Common purslane.

Application and Best Practices

As a post-emergence herbicide, Shtefazon is designed for flexible but disciplined application. With a recommended rate of 1.5–3 liters per hectare and the possibility of 1–2 applications per season, it fits well into various integrated pest management strategies. Because it is a contact-based product, thorough coverage of the foliage is essential for maximum effectiveness. Following the 30–45 day pre-harvest interval ensures compliance with safety standards and market requirements, maintaining the high quality of your final yield.
